Conduit

Couple separate parts of a conduit together: bridge the joints with a ground conductor
bonded to the conduit on each side of the joint. Also bond the conduits to the drive
enclosure and motor frame. Use separate conduits for input power, motor, brake
resistor, and control wiring. When conduit is employed, type MC continuous
corrugated aluminum armor cable or shielded cable is not required. A dedicated
ground cable is always required.
Note: Do not run motor wiring from more than one drive in the same conduit.

Armored cable / shielded power cable

Six-conductor (three phases and three ground) type MC continuous corrugated
aluminum armor cable with symmetrical grounds is available from the following
suppliers (trade names in parentheses):
• Anixter Wire & Cable (Philsheath)
• BICC General Corp (Philsheath)
• Rockbestos Co. (Gardex)
• Oaknite (CLX).
Shielded power cables are available from the following suppliers:
• Belden
• LAPPKABEL (ÖLFLEX)
• Pirelli.

Selecting the control cables



Shielding

All control cables must be shielded.
Use a double-shielded twisted pair cable (figure a below) for analog signals. Employ
one individually shielded pair for each signal. Do not use common return for different
analog signals.
